Can you share any details about the project you are running against? This looks like an issue with a particular package nuspec file.

[anuragpathak2608]

@coderpatros , Sorry can not share the project details.

Can you tell, what all things I can check at my end to make sure it runs successfully?

I received this error today. I reduced it to a sample project that includes the following packages.config file:

<?xml version="1.0" encoding="utf-8"?>
<packages>
  <package id="Microsoft.AspNet.Mvc.FixedDisplayModes" version="1.0.0" targetFramework="net40" />
</packages>

I see the same issue with v2.3.0. My project contains Microsoft.AspNet.Mvc.FixedDisplayModes 1.0.0 like the posted example.

Also had the same issue as @krisroe. Wondering if any updates.

I tried this and couldn't reproduce the issue with version 3.x.x. Probably it was solved by some other change or in a newer version of the NuGet package. If somebody still has this probably you can answer here and I will reopen the issue.
